>Organization:
University of Washington, Department of Physics
>Environment:

  Workstations in a DHCP environment with fixed (not PCMCIA/removable)
  ethernet cards.

>Description:

  In some instances, it is desireable to have a workstation with
  fixed (not PCMCIA/removable) ethernet cards to use DHCP for its
  interface configuration.  This patch allows an entry of

    ifconfig_<ifn>="DHCP"

  in the rc.conf file to mark the interface to be configured
  via DHCP and to do so upon system booting.



>How-To-Repeat:

	

>Fix:

  This patch takes the code for starting DHCP from etc/pccard_ether,
  and places a copy of it, with appropriate  "if"'s into rc.network.

  Once this patch is installed, an interface such as xl0 may be 
  configured using DHCP by putting ifconfig_xl0="DHCP" in the
  rc.conf file.
